    Are these upper bars properly placed?

    I want to run 18s with out cutting my floor so im using these short bars. But it doesnt look like the angles are right to me. this isnt my truck im putting the exact set up on a first gen 4 door. What do you think?

    The angles on those uppers are decent. Ideally, you want a 30-45 degree angle on the triangulated bars (45 in a perfect world). I, personally, would kick the axle mounts on those bars out closer to the frame to get a bit more angle on them just to be safe.

    One other thing you want to make sure is that the distance between the bottom mounts on the axle to the top mounts in the axle is slightly larger than the distance between the bottom mounts on the frame to the top mounts on the frame.
    Its hard to tell in those pics if its done right. Ideally you want the bars to intersect at the front bumper/grille if you were to extend them infinitely.

    the second part is called instant center. its set with the axle at ride hith. you actually want the lines to intersect at or just behind the largest mas in the front of the truck. we never drive with our rear ends aired up properly so putting it behind the radiator makes up for it.

    do you or any one else know what the first thing you are talking about is called? Id like to look up more information on it. thanks

    Both are in reference to instant center. If you look at the bars from the side, and follow their angles toward the front of the truck, where they intersect is instant center. Instant center is typically setup mostly for antisquat and weight transfer. 99% of the time, you will not need to worry about it on a street truck. Neutral instant center is pretty acceptable unless you're looking to hammer it at the track on a regular basis..

    Angle on the upper bars (as in your pics) deals more with roll center, and directly relates to side to side deflection. The more shallow the angle, the more your axle will walk from side to side, and you'll eventually break stuff. You want as much angle as humanly possible to kee that axle where it needs to be while you're driving...

    thanks for the info. I may be adding a v8 later and these california roads are not the best. The last thing I want is the rear end walking all over the place.

    P. Troy thats not my blazer thats the blazer my bars came off of. I will start a build thread as soon as i cut into my truck.

    Put the shocks on the outside of the frame rail and mount them to the lower link bars.
